A psychiatrist, who once practiced at an office on Route 447 in Smithfield Township, was taken to jail Friday after being charged with soliciting sex from someone he thought was a 13-year-old boy.

The boy was actually Det. Brian Webbe posing as a teenager.

Michael Nathaniel Kessler, 43, was arrested at his house in Cresco Friday morning by detectives from the Monroe County District Attorney's Office.

An investigation began in May when a woman called state police and told them she believed her 13-year-old son was being contacted by an adult on Facebook. She told police that the contact was suspicious. State police handed the case over to Monroe County detectives.

Webbe assumed the online identity of the child and soon heard from an adult using the name Marc Taylor. He later deduced that Marc Taylor was really Michael Kessler.

Earlier this month, Webbe said Kessler contacted him on Facebook and began a sexual conversation, according to court papers. He also offered to send him pornographic videos and allegedly sent a link to a pornographic video that showed adults having sex.

That same day, Kessler allegedly sent links to more porn videos and told Webbe he wanted to perform oral sex on Webbe (still posing as the teenager), according to police. Kessler also sent Webbe a picture of a nude male and claimed it was a photo of himself.

On June 18, police say Kessler sent Webbe another porn video and told him he wanted to re-enact the video with Webbe.

Webbe contacted Facebook, the American Registry of Internet Numbers and PenTeleData, an Internet service provider. They confirmed that the Facebook messages were sent from Kessler's house in Cresco, according to court papers.

Police raided Kessler's Barrett Township home Friday morning. After seizing a laptop and cellphone, they took Kessler into custody. He is charged with several felonies, including unlawful contact with a minor, and solicitation and attempt to possess child pornography.

He was taken to jail and bail was set at $50,000. Kessler is scheduled to appear in court for a preliminary hearing June 27.
